Brief  An affordable, green design integrating thermal efficiency from sustainable and environmentally friendly materials to meet the Passivhaus retrofit design standards.  Open spaces with maximum natural lighting  Research was put into identifying the most modern and energy efficient materials available to ensure a new way of life for students/occupants that does not cost the earth! Phase A o Modernisation of buildings layout and design (bathroom & kitchens). o Addition of elevators if deemed necessary o Reduction of energy consumption to retrofit passive house guidelines and levels o Sustainable energy production (secondary system). o Sustainable building materials & construction to be implemented as much as possible in the retrofitted building. o balcony renovation and/or addition of balconies, if deemed necessary o Management and cost calculations Phase B o Addition of a green roof and/or green facade o Addition of a student community house built in sustainable timber materials, containing: computer studio, toilets, relaxation/party room, small kitchen and outside terrace area. o Sustainable energy production (secondary system).

Why is it important? The efficient use of energy and the resulting cost savings are, nowadays, a concern not only of governments and officials as well as the general population. This concern increases when it becomes aware that it is not merely a matter of saving or, if you prefer not to spend, but also to preserve the environment that surrounds us. Thus, environmental concerns, such as CO2 emissions to the atmosphere and the consequent rise of the planet and increase of the ozone hole temperature, take paramount importance in our daily concerns.

Putting sensors in the corridors  The sensor can reduce energy consumption 30 % Reduction per corridor per year (kwh) Consumption per corridor without a sensor per year (kwh) Total (kwh) Consumption per corridor with a sensor per year (kwh) Total (kwh)

Savings with sensors per year Energy saving (kWh)Saving money € Investment (sensors) / UnityTotal €522.84€ Return on the investiment approximately in seven years

Green Roof + Solar Panels  48 solar panels produce kwh/year  By using a green roof on phase A we would save the environment from the emission of 710 kg CO2 compared to installing of another roof type.

34
Roof constructions Terrace boards for the Phase B:  Low maintenance  Eco-friendly materials  60% reused wood + 30% high density polyethylene (reused plastic)+10% colour + UV stabilizer  The lifespan of the boards of 25 to 30 years and are 90% reusable. Stands for terrace:  stands/feet are 100% reusable  not affected by any atmospheric impacts (UV/t)  The load of each foot is distributed to an area of 320 cm2
